My invention relates to improvements in spring wheels. and has for one'object to.

' group and these members being brought together to engage the plungerand being separated and diverging outwardly to engage the rim. l

My machine is illustrated more or less diagrammatically in the accompanying drawings herein.

Fig. l shows a side elevation in part 'section of my wheel with parts removed.

Fig. 2 is a section on an enlarged scale through Fig. l along the line 2-2.

Fig. 3 is a section along the line 3 3 of Fig. 1.

Like parts are indicated by like characters in the drawing.

I have illustrated my invention in connection with a rear wheel vthough it might equally well be vused in connection with a front wheel. f

. 'A is the central axle housing extending outwardly from the vehicle as shown. It

carries a roller bearing A. and is hollow to permit the Heating axle or'drive shaft A2 to project outwardly therethrough and to engage the bossAl3 on the wheel which is held in place on the shaft by 'means of a nut A4 enclosed by a hub cap A5.

B is the hub from which the boss A3 projects., This hubis mounted for rotation on the roller bearing A andf is radiallydrilled as at B. B2 are a series of abutments or pistons slidably mounted in the holesl Aor guides B and each outwardly pressed by ,the coil spring B3. B4, B5. are flexible spring spokesthere being four of them mounted in each abutmentV B2.V as indicated and terminate in the wheel rim B6 beingl spaced at their engagement with thern'njn a diamond shape.V One ot the These spokesV diverge be dispensed with or it may beL used in conv B8 is a Yrubber orf othersuitablefroad engagingtire.

garded as in a sense diagrammatic-` v The use and operation of'my invention areas follows: v

Parts are Yput together in the wheel, assembled in the shape and position shown in the drawings. When a Vload is put on the wheel each group of tourer more diverging spring spokes is loaded and is under com Vpression, the shapeV and arrangement beingv such that buckling or bending of the spokes is reduced to a minimum and so that the load is carried by the coil springs `supporting Vthe sliding abutments.l Y

The flexible spokes are subject to bending resultant upon sudden acceleration of the' force or supplement their cushioning of such stresses by the use of the single coil in the spoke as indicated thoughthis lcoil may be dispensed with or may be found in more thanV 190. i

one spoke of each group as the ease may be.

I claim:

l. In a spring wheel a rim', a plurality of spring spokes and a sliding spring supported abut-ment interposed between the ends 'of 95. ysaid spokes andthe center of the wheeLsaid spokes beingarranged in groups, therel being l one abutment foreach group, the spokes in each group diverging outwardly from they abutment to engage vthe wheel rim at spaced positions.
